Pneumatic Flange Type Explosion-proof Butterfly Valve
Summary:
Explosion-proof pneumatic butterfly valve is mainly composed of pneumatic actuator and butterfly valve, plus accessories explosion-proof electromagnetic directional valve, explosion-proof limit switch, explosion-proof locator, portable mechanism and so on. According to the different connection forms , it can be divided into flange type and clamp type. According to the use of different sealing materials, it can be divided into hard seal (high temperature and high pressure) and soft seal (normal temperature and pressure). Pneumatic explosion-proof butterfly valve is mainly used for medium in section. Valve positioner can also be assembled according to working conditions. Enter
4-20ma analog signal and 4-0.7mpa air source pressure to adjust and control medium flow and pressure, etc.
